Radiator removal 94pt 8v92
David,rad removal '94pt-8V92. I removed the panel below the louvered
door by drilling out 2 rivets and removing screws. Kept the fan oil radiator and aircon setup attached and moved both out of the way. dropped about 20 gallons of antifreeze. slid rad out 6 inches to clear fan as the fans shroud remains attached. lowered forklift about 8 inches then walked the entire radiator out across the forks. There are a row of sheetmetal screws that hold top rubber lipped air foil to the body(4pieces direct air into rad). I was able to remove only 3 of the 8? as you only have access to the back of the last screws . I loosened them with vice grips after stripping the thread with an airfile; then cut the screw off. I plan on tack welding a nut on the back side of the sheetmetal panel to reattach. Took full two hours, one man filled 4units of 5gallon pails with antifreeze I would guess rad weighs 120 to 175 lbs??? day prior I set the frame of the bus on blocks and sprayed all hose clamps, screws, nuts and bolts with liquid wrench. crusty bolts were coated with a finger full of greese. gotta watch fan, will reinstall with signboard strips taped in a pannel between fan and rad. simple 2x4 skid platform with jack inder installed radiator end would work better than forklift. forklift has no way to offset forward slope of jacked bus (will reinstall with 2x4's). fear I tweeked the drain pitcock when the weight rested on it as I lowered it in my pickup. I will post the rod cost or shop recomendaton. You gain little additional access to hard to reach aircompressor cooling lines with rad removed.

Nice job Greg,
While it's out I'm sure you'll be back there spraying DP40, or POR15, or one of the Eastman "paint over rust" products. I know I would. Pictures would be great. David Brady '02 LXi, Ca -----Original Message----- |

Radiator rodding quote $650.00 stewarts industrial radiator. Owner
Wally shop is one mile from CCW Riverside. recore is over two grand. 951-683-5054 http://local.yahoo.com/info-36959945 My rad is 60% blocked with rust-mud and only giving 10% of its ability (claim two shops) I used Stewart because they came recomended by several sources and his rodding price was $400 cheaper than one other shop. Stewart tech and owner Wally asked me to bring in the transmission cooler for a flow test and look. He ex-plained that if the trans cooler is blocked (trans cooler is placed after rad exit)it wont allow good flow and the rad will get backed up also. Wally claimed that the OEM product is way good quality and most issues requiring recore of that brand are from exterior degrading (salt and road hazzard). I dropped the trans cooler and will post pics of the guts. looks like a catalitic converter, 400 journals. GregoryO'Connor 94ptRomolandCa |

Greg, I put a new core in mine, with about a 30% increase in cooling surface. Cost was right at $1,800, plus lots of shop time. Terry Terry Neal |

Radiator ROD is what it is...push a rod through each tube, and flow/pressure test after. Anyone doing less is taking your money.

Dan, There are several was to do it. On the radiators we have in the
bus you will notice a big line of bolts that hold the top tank to the core (center finns) the shop can remove only one tank and push a flat strap solid rod in the many journals to open up and clean the passage. I have this done to my dump truck every 2 to 3 years ($250.00). My bus radiator was so clogged that both tanks needed to be opened so the tech could push and pull rods from both ends. I watched the guy cut rod stock from a roll and sharpen it on a wheel befor he attempted to push the flat stock thru the journal. the journals close to the sides cake up quicker (frame heat sink) and in worst case they can be soldered closed and not used. The trans cooler on my bus is a tank where the trans oil is flowed over tubes encased in a larger pipe. the tubes (400tubes 12 inches long) are connected to the radiator ouput. the antifreeze flows thru the tubes then into the engine. One forum member?? had to replace a tranny when one of the many tubes in this heat exchanger leaked and pushed radiator fluid into the tranny. The tech doesnt want to push a rod thru the tranny exchanger tube because he fears making a weak spot and having it show up later with water in the tranny. he plans on using heat and chemicals to clean it and inspect it. the heat exchanger on my tranny is a BorgWarner and not serevisable. if he finds issue I will have to buy a new one. ($?,???.??) here is kinda a diagram of heat exchanger term ;Tube=Radiator fluid and ;Shell=Trans oil http://www.cheresources.com/shell_tube_h...Image5.gif GregoryO'Connor 94ptRomolandCa --- In WanderlodgeForum@yahoogroups.com, "Dan Williams" > > Greg, tell me if I am wrong but I don't think radiator shops actually "rod" > the radiator.

I paid $3800 last summer for the re-core up here. Makes me feel bad reading your post Greg. Oh well, just money.
